Read some of the articles I have posted. Check out some of the links. Call or email teachers and ask them lots of questions. Understand your reasons for taking the class and be clear about that with any potential teacher. Ask for her experience and training (she should have both – check out my articles on “What to expect” and links to recognized teacher training programmes). Take classes with more than one teacher, and compare. Talk to to other students. Go to a dance event. Eventually you will find the teacher who is right for you. Along the way, you will learn about what you do and don’t like, how your learn best, and what style of the dance suites you.
